DIESEL CYCLE
so the efficiency came out to 860% which should be wrong (unless the numbers you gave us actually give us this answer which i doubt you would because nothing is ever 100% efficient).i actually may have taken the inverse if i did the correct efficiency would be 11.6 % which sounds more realistic.

active physics question 6


active physics question 7


active physics question 8

pressure vs volume graph used to find work when shifting points,internal energy at certain points,and the change in internal energy between points.below  we did the same thing except the shape if the process is different. adiabatic and isothermal work are calculated differently.

in this lab we plot the temperature vs Volume (in CCs). this demonstrates the direct relationship between pressure and volume. our graph slope is 1.59 degrees Celsius/cc.our other values were 32.5 and .2368. so our air has a mass of32g/mol since its nitrogen. so nR= the square root of the product of our three constants. which comes out to 3.5.








the left picture shows the relationships of Pressure,work,force and area. if volume is constant work is equal to pressure times volume.

frequncy of red light and green light wavelengths.
a lab set up in which we find how much a wheel turns due to a
hollow rod that is expanding due to being heated by steam in side it.
different material have different coefficients of thermal expansion.
this determines how much of a temperature change is
needed to cause that material to expand a certain distance


calculations to find the rotation of the wheel.

more calculations
even more calculations.






this is the data recorded from logger pro that gives the actual angle change  of the wheel
and the temperature change.


prediction of how the temperature for water rises

lab set up to find the latent heat required to boil water.

the graph of the water temp when
trying to find the latent heat.
our calculations for the latent heat and the uncertainty.


our latent heat value was 1,113,000 J/kg and the Standard deviation was 814,000J/kg which brings our latent heat value to 1,927,000 J/kg which is almost near 2,256,000 J/kg.
Our Value came out low because of the way the lab was preformed the final mass we measured was wrong because the water continued to evaporate even after we turned off the water immersion coil.
Another error is from not having the water on scale to make our values more accurate.


Calculations to find the final temperature of ice given a certain
amount of heat.

Mass of water needed to get ice to a certain temperature and
the liquid water to freeze.


predictions of pressure relationship graphs and variable
calculations of pressure.
the graph of pressure and volume change.
